Facial hair matters. It matters a lot in a show like "Game of Thrones" where everyone is supposed to look grizzled and bad-ass. Sometimes a clean-shaven guy just can't pull off bad ass. If you were ever skeptical of the science behind women being more attracted to men with beards, a quick glance through this post should dispel that skepticism. To put it kindly, most "Game of Thrones" characters without their beards look like goobers. This is why, fellas, once you grow a beard, you never go back. Your face can't sustain the trauma. It's just too weird.

Hell, Iain Glen doesn't even sport that much facial hair in "Game of Thrones" but I didn't even realize he was the guy from "Downton Abby" until today.
